Hey, Karen. Did you know that cats are natural predators? Their sharp eyesight and nearly prehensile tails give them an edge in the deadly game of natural selection.

That's neat! Tell me more. They don't talk about kitties in school.

They've survived for aeons because of their lightning reflexes and sharp claws. Did you know, they kill an average of three hundred million mice a year?

Ewww... my kitty doesn't kill things!

Well, not anymore, she doesn't. You see, Karen, millions of years of intricate evolutionary progress hasn't allowed the common feline to differentiate between ordinary field mice and field mice that have been coated in plastic explosive.
